I'll repeat what I said pages ago. Peace of mind while driving anywhere beyond the driveway can only come from biting the bullet, pulling the engine, thoroughly flushing, cleaning, inspecting, and reassembling. YOU can do it mostly yourself .. it's not brain surgery. This forum is a rich source of rebuilding help. Also my 2 cents. Good luck.
I completely agree.

However, I am stuck, I rebroke my chestplate overdoing things trying to work on the car myself.

My neighbor is nice enough to help me get the car back together. I'll inspect the rockers, and possibly the lifters if I can (special heads, I'll have to source out gaskets).

The rest of the oil in the pan looks OK, no chucks or shavings, so I'm hoping this is just the last bits of roller bearings from the previously failed rocker that I was not informed about before buying the car.

Hopefully, with the last bits gone, and new oil/clean pan/inspected rockers, that I hopefully will have the motor running again.

Then, if I decide to keep the car, I'll start saving to properly go through the engine.

Mike,
I think most on this forum have run into problems. Right now my cat just clicks when I turn the key, even with a new battery. I'll trouble shoot tomorrow. It's just part of owning one of the greatest cars ever produced. I know I can't feel your physical pain from your surgery, my dad had 2 triple bypasses and I remember what he went through. You have been a super man with your determination to get things sorted out and I applaud you. I would just kick back have a beer and tackle the issue another day.

When you say you went on the lift, was it a typical lift and you were level and the Pantera was lifted or did you drive up onto the lift/ramp on an angle that could have dislodged the piece into the pickup. My self I would:
Assume the rockers are OK because you said it ran perfectly and you were told one broke in the past.

Check the dizzy to make sure it spins freely.

Look at the cam gear for any chipped teeth.

Get a Moroso pump drive shaft.

Hot tank the pan to get everything out.

Put the pan on.

Stab the dizzy

Then drive it locally till you get confidence in it's dependability then have fun and relax.

Take care of your self first and snow white second, we want to read all your happy tales with snow white in the future.

Curt
Thanks very much.

Yeah, I've been full speed ahead until that pan came off. I needed to find out what was jamming that pump.

Turns out I find out about a previous rocker failure that was not disclosed when I bought the car.

It DOES look though, like those 2 or 3 bits are all that's in there.

If there's a way to flush the engine from above to try and wash anything bad down and away before we button the car back up, I'd be game for that.

As long as the other rockers check out OK, and I don't find any more bearing bits anywhere, the plan is (with Chuck's help) to button the car back up, and hope that does the trick.

The motor ran super sweet before this glitch. Luckily it never even made one revolution under power, so no damage (other than the dents I put in the old pump rotor by cranking the motor over by hand) was done, the engine never ran without oil pressure.

All the plugs are removed so when it's time, I'll be able to crank the motor over with no loads until I see oil pressure. It's been dry-cranked enough.

If I can get gaskets for the Yates heads, I'll pull the injection and top cover off so I can inspect the lifters as well.

All of this goes completely against what my common sense tells me, which is tear the engine down and rebuild it, but I just don't have the time, money, or tools to do that job presently.

Well, this is one of the issues with this kind of an engine on the street. The owner.

People just don't get what it means that they (race engines) are subject to unique, separate and individual issues?

This isn't a new story. In fact it's getting kind of old.



Back in the "olden days" if you happen to buy a "race car" from Shelby, you got the stock, as Ford built 289hp, AND YOU put in YOUR OWN race engine.

This eliminated the possibility of hard feelings between Shelby and the new owner over a broken and expensive race engine.

There isn't a shred of doubt on my part, and probably a lot of other people here, that for all intents and purposes this is a FULLY CLAPPED OUT RACE ENGINE, "with all the rights and privileges". It's going to act like one AND BREAK LIKE ONE. GET OVER IT BECAUSE IT WILL BREAK AGAIN! Period.

IT IS NOT GOING TO EXPERIENCE THE SAME LONGEVITY AS A "PRODUCTION ENGINE".

Having said that, NOW you do what every race team would do here, which Roger did, clean all the mess out, put in a new part, and get on with it. I like to think of that as "the first day of the rest of my life." It's just life with an engine like this. It IS a HARSH REALITY.

You put big ugly magnets on this thing to trap the shrapnel that gets loose and when the engine gets to the point where the peripheral damage gets too extensive, you build another one OR put in the spare that you have ready waiting in the wings simply because "you" understood all of this and expect that will happen at some point, sooner or later?

This engine has the same likeliness of surviving that you will "go through one "race" season" on one engine as an "iceberg in Hell" has a chance of surviving.



All that stuff about, "modern roller lifter camshafts being dependable and having the bugs worked out"...well where is it? Doesn't matter this is a rocker arm and not a lifter. LUCKY FOR YOU that's all it is and NOT a lifter! Roll Eyes



Like you said, this is a "race engine", but you already knew this before you bought the car right? Wink

Cheers

Agree with PanteraDoug completely. Back in the "old" days when you had a car with a engine like this you worked on it all week to run it on weekends, part of life. Today though with computer controlled crate engines, same power and 1000% better reliability.
I've got a buddy who has a 36 foot Specter CAT with 2-575 SC's in the back. He's got one speed, wide open at 107 to 118 mph (depending on beer boxes and chicas) for years. Work done on both engines, change the oil and filters. Smiler
I see this as a blessing. Catching a problem that could lead to a destroyed engine before that happens.

I have pulled out of a pre-paid dyno session because of just this type of warning and it saved me big time.

This is a perfect opportunity to go thru and make sure everything is all right. Race bred engines don't last forever, but with frequent pull downs, parts that do wear out can be replaced before a catastrophe happens. Without changing everything, the easiest way to reduce potential problems is to go to slightly milder cam. The weak link in pushrod engines is the valvetrain.

Just my 2 cents.
.
Fragments have a way of hiding in nooks and crannies. If Mike wants to wash and run it, that is his choice, but I think it is easy to stand back and say run it when you don't have any skin in the game. Mike has already stated his budget is maxed. Grenade it far enough and most everything will need replacing.

Soft brass or aluminum is one thing, steel, graphite steel and iron fragments are another all together.

Sounds like he has made some good friends that can lend a hand and offer guidance. Soon as he heals up would be a great opportunity to do it right.

Again, just My 4 cents.
.
Of course, the right thing to do is fix everything properly.

The engine did run perfectly. Until I changed the oil, where it never even started (so no damage, at least then and there)

I'm cleaning out the pan, installing a thinner screen on the pickup, adding magnets that should catch any more bits.

Chuck has been nice enough to help me get the engine back together.

As it is, I hope it'll be fine cleaning things up, and running it. That's what Roger has told me to do.
I think the bits were living happily in the bottom of the case, and when I poured the new oil into the engine, it washed some bits over the little lip in the pan section, and the offending bit was sucked in instantly. The motor never even made one revolution, so no new damage.
So I figure now all the bits are gone, engine is OK, I have 2 BIG supermagnets now in the pan, and I installed a finer mesh screen on the pickup. The engine will run again soon.

I'll start saving then for a proper rebuild, when I can handle it financially.

I am just disgusted though. This is not what I intended to buy, but I'm here, so it's full speed ahead until it's running again.
Mike, One step at a time. If it is your decision to clean and put it back together fine go ahead. Don't warp your mind with thoughts of I need to same my money to rebuild the engine unit and unless you have to. Don't loose sight this is a FORD. If this engine becomes destroyed because you didn't get all the rollers out of there it can be replaced with another engine. Patience patience patience. This is supposed to be fun that's why we are called Hobbyists and this is our hobby. Look at it this way - at least you don't have to worry about getting this car running go that you have something to drive to work on Monday morning. LOL Its supposed to be fun. Don't stress out.
If the assumed to needle bearing pieces came from one or more of the current lifters, it will be obvious to you if you measure the rocker arm lash on each lifter and discover one that is excessive. If they are all in spec, it was probably from the previous lifter that was replaced. You can buy those big round flat magnets at Harbor Freight and stick them to the bottom of the oil pan to capture and discourage future ferrous pieces from finding their way into your oil pump.
Have I missed something? I've heard about "roller needles" and I've seen a pic of a fragment that isn't a roller needle. And I've heard about a prior rocker failure which MIGHT be the source of the debris. But I didn't hear any plan to check all existing sources of the roller needles. The magnets and screens may stop metallic fragments from getting in the pump but if the failure is a CURRENT component (rocker, lifter, cam bearing) then firing up and running will result in another damage event. And the fact that it ran for a while doesn't preclude an existing damaged component. You don't have to pull the engine to check other sources of debris. Good insurance policy.
The rockers I checked today. All look to be in perfect condition, so I am assuming the debris came from the previous rocker failure.

There doesn't seem to be any current failures existing (except for the jammed oil pump) so I hope the magnets, and cleaning things, and new oil pump along with finer mesh screen on the pickup should have the motor back running fine.

I was not given the engines history, it would have been nice to know about that. IMO that's the kind of history you mention when selling a top-dollar engine for top-dollar, but that's just me.

I was told the motor was bulletproof (of course I didn't expect the engine to last forever, but I did expect what I was being told I was buying. It turns out that was not the case.

I haven't asked whether the screen is too fine. Monday I plan to make some calls to Aviad and find out. The pickup box is 2"x3" so it's got a lot of area compared to the hole on the pickup tube.

What I CANNOT have happen, is have another chuck of something stop my engine dead cold the way it happened this time.

I'm installing supermagnets into the pan, so they should help pick up anything that might be left in the motor, and the screen mesh is small enough that the offending roller pins cannot make their way through and cause this issue again.

I also plan on dropping the oil weight from 20-50 to 10-40, which should help if the screen does restrict the oil pickup. My oil pressures were very high anyways, so I think the drop in oil weight will be tolerated).

I know also that hot oil is much thinner, and once hot I really don't think I'll have any flow issues with the finer screen, so a good warmup of the oil will be part of my startup procedure (it actually always has been. I know it takes a good 10 minutes for the oil to get hot in any engine).

I'm doing what I can with what I have, until I can deal with this and go through the engine and gearbox properly. I should have enough saved by next year to do those things.

It would have been really nice to have been told about the rocker failure before I bought the car. I was told the engine never had any issues, had low miles (like 5000-6000 miles) and was strong and should last with proper maintenance.

I was fully prepared to do normal maintenance, valve adjustments, oil changes, occasional repairs on parts that fail on a 40-plus year old car (like going through the entire wiring system when I got the car home, because basically nothing worked, no blinkers, no taillights, one headlight, no backup lights, tach only working occasionally) all those things were fun to fix, and what I expected.

Having the motor die after an oil change, and then to find out about a previous rocker failure that sent steel bits all through the engine, THAT, I should have been told about IMO.

I have things cleaned up, the bits are gone, magnets in place, smaller mesh screen in place, the car is ready to reinstall the new oil pump and pan and finish all the other things that need to be done to get the car back running (bolt-in crossmember, new water hoses, distributor pin fixed AGAIN and reinstalled, plugs installed after oil pressure is confirmed, plug wires put back, valve covers installed, air cleaners installed, chrome side covers installed, seats and firewall installed, and much more). It's a huge job. Not what I had planned on when I dropped my life savings on the car.

Sorry Mike if I'm contributing to your concerns, but is this mesh a standard thing? The mesh if too fine may restrict oil entering so you may lose pressure at high rpm?

I don't know, just guessing, I wouldn't dare do that. Have others done that and lived happily with it?
Thanks,

I already have that piece you gave the link to.

The finer mesh screen is the only way I can guarantee no more bits make their way into the pump. The screen on the pickup is too coarse and will allow another piece of metal or roller pin through easily.

I'll inquire tomorrow, but I'd rather run thinner oil, and take longer to warm up the engine oil, than I would dealing with this mess again.

I'll inquire with Aviad in the morning.
